Merging symmetry projection methods with coupled cluster theory: Lessons from the Lipkin model Hamiltonian
Jacob M Wahlen-Strothman, Thomas M. Henderson, Matthew R. Hermes +5
Coupled cluster and symmetry projected Hartree-Fock are two central paradigms in electronic structure theory. However, they are very different. Single reference coupled cluster is…

Projected Hartree Fock Theory as a Polynomial Similarity Transformation Theory of Single Excitations
Yiheng Qiu, Thomas M. Henderson, Gustavo E. Scuseria
Spin-projected Hartree-Fock is introduced as a particle-hole excitation ansatz over a symmetry-adapted reference determinant. Remarkably, this expansion has an analytic expression…
